A TTOR/VEYS Patented July 18, 1950 WINDOW Harris E. Vaughn, Reno, New: Application March 16, 1948, Serial No. 15,169 i This invention is a two part window comprising upper and lower sash which are linked together by links, the links being pivoted to the stiles of the two sash at points adjacent the meeting rails thereof. 7 a

Both the upper and lower sash can swing inwardly; the upper sash swings on a horizontal axis at about the level of its upper-rail, while the lower sash swings about a horizontal axis at about the level of itslower rail.

Both upper and lower sash engage with the side jambs of the window frame in which they are mounted, on these horizontal pivotal axes, and it is an important object and feature of the invention that both upper and lower sash may be readily and quickly removed from the window frame simply by. disengagement of these two pivotal axes from the side jambs of the window.

Each of the two sash may be positioned at a desired level independently of the other sash. This feature, in combination with the link connection adjacent the meeting rails of the two sash, enables the two sash to be. positioned in various relative positions, such as the following:

A. The upper sash is slightly lowered and in a vertical plane, with the lower sash inclined outwardly.

B. The upper sash slightly lowered and inclined outwardly with the lower sash in a vertical plane.

C. Both sash at an angle inwardly, one of the sash being lowered or raised from normal position.

D. Upper sash at an angle inwardly, with the lower sash verticalland raised above its normal position.

E. Both sash in closed position, in the same vertical plane.

The two sash, when the window is closed, are in the same vertical plane, the meeting rails fitting together with a rabbeted construction. With this arrangement one sash, preferably the lower sash, which has a shoulder that overlaps the other, is provided with simple pivoted latches engageable with the side jambs, so that these latches hold both sash in the closed position.

In relatively small installations, where the sashes are not heavy,' no counter-balancing springs or weights "are necessary. However, where heavy sash are involved, counter-weights Fig. 1 is a perspective view showing the upper and lower sash separated from the window frame. V H

Figs. 2, 3,4,5 and 6 are diagrammatic views illustrating various relative positions that may be assumed by the upper and lower sash.

or springs may be provided for facilitating the Fig. 9 is a view of a detail of the friction grip device. v v

Fig. 10 is a side view of the'friction grip device.

Referring now to these drawings, the window of this invention comprises a lower sash indicated generally at 2, comprising stiles 4 and 6, upper rail 8 and lower rail Ill. The upper sash indicated generally at l2,"comp'rises stiles and I6, upper rail I8 and lower-rail 20.

The lower rail [0 of the lower sa'sh is provided in its bottom edge with a pivot rod 22, the ends of which project to theright and 'left'beyond the outer edges of the stiles 4 and 6, to form pivot pins. 1 1

The upper rail l8 of the upper sash is provided in its top edge with a similar pivotal rod'24, the ends of which project beyond the outer edges of stiles M-and l6 to'form pivot pins.

. Coming now to an important feature of the invention, the two sash 2 and I2 are linked together near their meeting rails by means of links 26, pivoted respectively to the stiles at 28 and 30. These links 26 are of relatively thin sheet metal. I The meeting rails 8 and 20 are rabbeted form+ ing shoulders 32 and 33. The shoulder 32 of rail lioverlaps shoulder 33 of rail -All, so that in closed position the two rails and also the two sash? and ,M are inthe same plane.

The upper rail 8 of the lower sash is provided with latches 3 Lof any desired type, conveniently latches turning on a horizontal axis and engagingin recesses 35. These latcheshold both sash closed, onaccountof the overlapping shoulders 32and33 The two part window just described is mounted in a window frame comprising asill 4 ll, side jambs 42 and M, and head jamb '46, the side ja bs and head jamb being provided with the usual blind stop '48.

Just within blind stop 48, the head jamb is provided with a horizontalg'ro ove 5i) and in the same plane with 50, the side jambs are provided P iiims ii e sr s 's fiisr snd s P t 11111 length of the jambs. The side jambs are also provided with downwardly and inwardly inclined notches or sockets 54. The side jambs are also provided with horizontal grooves 56 for accommodating the projecting pivots 22 and 24, for use in putting the window in the frame or removing it therefrom.

The sill 40 is provided with a horizontal groove 51, registering at its ends with vertical grooves 52, for accommodating pivot rod 22.

To assemble the window, the projecting ends of pivot 22 is slid into slots 56 and then the sash is dropped to the sill, the pivots sliding in grooves 52. Then the ends of upper pivot 24 are passed through slots 56 and the upper sash moved all.

the way up as far as it will go; then the lower sash is moved inwardly into the same plane, with the upper sash, so that the rails overlap, and both sash are held by turning latches 34 which engage in recesses or keepers 35 in the side jamb. Thej'window may be readily removed simply by reversing these operations.

, With. the construction described, the two sash may take various relative positions for example, a's'follows:

As shown in .Fig. '3, the upper sash is lowered Slightly and held by pivots 24 in one pair of notches 54, while the lower sash is angled inwardly, to deflect incoming air upwardly. Some air circulation would also take place over the top of thesupper sash. The upper sash could, if desired, remain all the way up, with the lower sash angled. .inwardly- In Fig. 4, both sash are angled inwardly, one

orb'oth, iidesired, being moved up or down from the, sill or top lamb. Ventilation would mainly be atv the top-of the window.

In Fig.5, the. lower sash remains in its lowered iierticalpositiomthe upper sash being nearly all the way down. Ventilation would mainly be at the top, \vith'some air deflection downwardly.

.In Fig. 6,, the, lower sash is raised and held by pivots 22 in .one pair of notches 54, while the upper sash, is angled inwardly to deflect air down,- wardly. An important .teature .in achieving the above described positions is the connecting link 26, whereby either meeting rail .of either sash may be positioned well outwardly, or well inwardly, with respect to the adjacent rail of the other sash, for deflecting incoming air either .upwardly or downwardly.

The factthateither upper or lower .sash may be positioned at various levels, in cooperation, with, the connecting .pivotal link 26, provides a two :Part window which may be positioned in many positions, where the upper sash is all the .Way up or part way down, .or the .lower sash is all the way down or part way up, and in any of these positions either or both windows may be angled outwardly into the room, with either meeting rail outwardly of and overlapping the other meeting rail.

Furthermore, as already mentioned, the Window may be very quickly assembled and disassembled. The construction is relatively simple and involves a minimum (if-relatively expensive metallic fittings.

v .As already noted, counterweights or springs may be-provided for heavy sash, if desired, as is well understood in this art.

Inmost instances, the two sash will naturally remain in the various positions in which they maybe placed." However, in order to, hold the two sash in any desired adjusted position, one

4 I or two friction operated devices may be associated with each connecting link 26. These friction devices, shown in Figs. 8, 9 and 10, impose enough force to hold the two sash in any position in which they may be placed, but this frictional force may be readily overcome manually to move the sash to other positions, the friction holding the sash in such new position.

Referring now to Figs. 8, 9 and 10, one or both ends of link 26, corresponding to link 26, is provided with a thickened head 60, radially serrated or roughened, on one side, as at 62. The serrations of heads 60 engage similar serrations 64 in a head 66, spring pressed by spring 61 against head 60. The force exerted by the springs 61 may be varied in any way desired. Head 66 is locked against rotary movement and is mounted for movement, against spring 61, in a housing 68 recessed into the stiles of the two sash. For lighter windows, one such friction grip device may be used with each link 26; for heavier windows, two may be used with each link. Weatherstripping may be used if desired. As shown at the left of 7, Weatherstripping 10, of felt or the like, may be secured in recesses 12 in the blind stop 48, all the. way around, the felt being positioned so as to be. compressed by and so to fit tightly against, the stiles and rails of the window. As shown at the right. of Fig. '7, weatherstripping 14, of felt or the like, is secured to the blind stop, so as to be compressed by the stiles and rails to make a tight joint. The Weatherstripping T2; or 14 may be sheathed with a thin protecting strip 1.6 of metal or the like.

While the invention has been described in some detail, it should be understood that the invention is. not to be limited to these details, but may be carried. out in other ways.
